Leinuosen 60 Pieces Pin Keepers Locking Clasp Pin Backs Replacement with Wrench (Silver Color, 6 x 5 mm)

I saw these advertised on Facebook, looked good as I have a number of pins, but they tend to lose the backs, which means I lose the pins. Someone mentioned you could get them cheaper at Amazon so I bought them here. Each little package of ten come with a tiny Allen wrench for the tiny little screws, because if you lose the little wrench you may have trouble finding another one this small. Happy with purchase.

Hold great, backers will never pop off again. Be careful not to over tighten or you can bend your posts.

No more losing pins or pin backs

I collect enamel pins and this makes it so easy to not lose them! The size is needed but is difficult for people who cannot hold small items. It's a little bigger than the plastic covers they put on the back of earrings. We have bought 150 so far and will continue.

These things are amazing! The pinbacks supplied by the makers of trading pins are completely useless. I've lost a couple of pins that I truly enjoyed having. Upon research and finding these secure pinbacks, I can wear my pinfield lanyard with confidence that I will return home with all my pins securely in place. And true value for the money. At Disney, a package of 10 is $10! I'm down to just under two packages, time to reorder! Highly recommend!!

I have a pin collection on my jacket. I had issues in the car with the seat belt pulling the pin backs off.These solved that problem completely.

I don't mind attaching the pin with the Allen key, even find it helps make it more secure. I've been using these on pins, on an every day bag and absolutely no problems so far. Very happy.

They do their job and are pretty darn secure but if the cloth of whatever you're attaching these to is on the thicker side, you might experience pins still falling off.

Most badges/pins now have the short pins sticking straight out of the back, rather than the older, more fiddly safety-pin kind of arrangement. That's great, they sit flush against whatever you put them on. However, the backing-pieces for some badges are useless at actually holding it on, especially the rubberised ones. So, these provide a simple, robust solution meaning that you won't lose your precious badges: I've replaced all my backings with these, and it also stops/reduces the amount that the badge can pivot around too.The only, tiny caveat is that, depending on the thickness of the material you have the badge mounted on, there may be a very small amount of the pin protruding from the end of the metal collar. However, they are not that sharp, but if you have badges on a pocket that you use a lot, it's something to be aware of (not an issue for me, as I never use the top pockets on coats, which is where most of mine are). I guess you could move the metal collar closer to the end, to counteract this.One tip too: It's much easier to start the small grub-screw in the metal collar if you first put it on the long end of the hex-key. Then it is easy to align it with the threads on the collar, and screw it in by maybe a turn, to start it off, all using the hex-key to hold the screw. After this, you can put it on the badge-pin and finish locking it on.

Pros: If you someone that collects lots of Pins and wants to display them on a jacket or bag and do not want to lose them then this item will be one for you. When you fasten one of these to your pins its not going to come off any time soon that is for sure unless you break the pin itself or you have a rip in what every the pin was attached too.Cons: To acutally fasten your pin with this Locking clasp is by no means easy specially if you have big hands. You have a very small black stopper that you insert into the side of the clasp using a thin metal wrench, this in turn will then hold the clasp finally against the pin. Yet time again as you try to insert this the black stopper falls off the wrench and also with it being black you will not be able to see the hole on the stopper to insert the wrench into again leading to more frustration.I found with this brand that nearly all the pins i attached the claps too the tops of the pins will poking out the top. So they recommend for the likes of lanyard or thin clothes as you mostly likely get scratched cause of this.

These popped up in my Amazon list apropos nothing, and I couldn't figure out what they were from the picture. Little did I realise they were the solution to a problem I hadn't acknowledged I had, namely, never wearing pin-badges because they had sentimental value and I was scared they would drop off due to flimsy backings. These babies are solid. Once on, a badge is not coming without ripping the fabric or using the allan key provided (or another one). Fantasticly useful things.

The media could not be loaded.  Helps me keep my many badges on my bike jacket.

That's it... Once the pin is secured, it'll never move again unless you want it to.No more worries about your beloved pin falling off.I would really reccomend!
